Abstract

This disclosure relates to articles that include a tightening mechanism, such as reel-based lace tightening mechanism, configured to tighten the article by rotation of a knob. The articles can include a concealing portion that is configured to conceal or protect at least a portion of the tightening mechanism, such as the knob. The concealing portion can be configured to prevent unintentional actuation of the tightening mechanism, such as during contact sports. The concealing portion can be configured to hide the tightening mechanism from view to improve the visual appearance of the article. The concealing portion can be collapsible such that a user can press the concealing portion down to expose the knob of the tightening mechanism.

Claims

1. A shoe, comprising:

an upper having a first side and a second side;

a tightening mechanism coupled to the upper and positioned on a first side of the shoe, the tightening mechanism comprising a rotatable knob, wherein rotation of the knob in a tightening direction draws the first side and the second side toward one another to thereby tighten the shoe; and

a concealing portion extending outward from the upper and at least partially radially surrounding the tightening mechanism so as to aid in protecting the tightening mechanism from unintentional contact with objects, the concealing portion including a compressible material that is positioned under a top layer of the upper and the concealing portion including a first portion that extends outward from the upper farther than a second portion such that, via the second portion, the tightening mechanism is actuatable without displacement of the concealing portion, and wherein the first portion comprises an arcuate configuration so that, immediately adjacent the tightening mechanism, a top surface of the tightening mechanism is substantially flush with an outer surface of the concealing portion and so that, a radial distance from the tightening mechanism, the concealing portion is substantially flush with the upper.

2. The article of claim 1, wherein the compressible material comprises a foam material having a durometer of between about 10 and about 25 Shore A.

3. The article of claim 1, wherein the concealing portion is formed as an integral portion of the shoe.

4. The article of claim 3, wherein the concealing portion includes a recess that extends through the side wall, and wherein the tightening mechanism is disposed through the recess.

5. The article of claim 4, further comprising a base layer that is positioned beneath the recess of the concealing portion.

6. An article, comprising:

a base material;

a tightening mechanism coupled to the base material, the tightening mechanism comprising a rotatable knob, wherein rotation of the knob in a tightening direction tightens the article; and

a concealing portion extending upward from the base material and at least partially radially surrounding the tightening mechanism, the concealing portion including a compressible material comprising a compressible foam, wherein at least a portion of the rotatable knob is rearward of an outer surface of the concealing portion;

wherein the concealing portion comprises a second material that is less compressible than the compressible foam, the second material at least partially radially surrounding the tightening mechanism.

7. The article of claim 6, wherein a majority of the rotatable knob is rearward of the outer surface of the concealing portion.

8. The article of claim 6, wherein substantially the entire rotatable knob is rearward of the outer surface of the concealing portion.

9. The article of claim 6, wherein a top surface of the rotatable knob is substantially flush with the outer surface of the concealing portion.

10. The article of claim 6, wherein the compressible material is positioned under a top layer of the concealing portion, and wherein the concealing portion provides a transition between the tightening mechanism and the base material.

11. The article of claim 6, wherein the compressible foam is resilient so as to resume an uncompressed shape when a compressing force is not applied.

12. The article of claim 6, wherein the concealing portion is formed as an integral portion of the article.

13. The article of claim 6, wherein the concealing portion comprises a recess within which the tightening mechanism is positioned.

14. The article of claim 6, wherein the base material comprises a hole and at least a portion of the tightening mechanism extends through the hole in the base material.

15. The article of claim 6, wherein the concealing portion radially surrounds the tightening mechanism by a full 360 degrees.

16. The article of claim 6, wherein the concealing portion comprises a first area and a second area, and wherein a height of the first area of the concealing portion is greater than a height of the second area of the concealing portion such that the rotatable knob is more exposed at the second area than at the first area.

17. A method of making an article, the method comprising:

providing a base material;

coupling a tightening mechanism to the base material, the tightening mechanism comprising a rotatable knob that is configured to tighten the article upon rotation of the knob in a tightening direction; and

positioning a concealing portion so as to at least partially radially surround the tightening mechanism, the concealing portion including a compressible material and the concealing portion extending upward from the base material;

wherein the concealing portion comprises an arcuate configuration so that, immediately adjacent the rotatable knob, a top surface of the rotatable knob is substantially flush with an outer surface of the concealing portion and so that, a radial distance from the rotatable knob, the concealing portion is substantially flush with an outer surface of the article.

18. The method of claim 17, wherein the concealing portion is positioned so that a majority of the rotatable knob is rearward of the outer surface of the concealing portion.

19. The method of claim 17, wherein the concealing portion is positioned so that substantially the entire rotatable knob is rearward of the outer surface of the concealing portion.

20. The method of claim 17, wherein the compressible material is positioned under a top layer of the concealing portion, and wherein the concealing portion provides a transition between the tightening mechanism and the base material.

21. The method of claim 20, wherein the compressible material comprises compressible foam.

22. The method of claim 21, wherein the concealing portion further comprises a second material that is less compressible than the compressible foam, the second material at least partially radially surrounding the tightening mechanism.

23. The method of claim 21, wherein the compressible foam is resilient so as to resume an uncompressed shape when a compressing force is not applied.

24. The method of claim 17, wherein the concealing portion is formed as an integral portion of the article.

25. The method of claim 17, wherein the base material comprises a hole and coupling the tightening mechanism to the base material comprises positioning the tightening mechanism such that at least a portion of the tightening mechanism extends through the hole in the base material.

26. The method of claim 17, wherein the concealing portion radially surrounds the tightening mechanism by a full 360 degrees.

27. The method of claim 17, wherein the concealing portion comprises a first area and a second area, and wherein a height of the first area of the concealing portion is greater than a height of the second area of the concealing portion such that the rotatable knob is more exposed at the second area than at the first area.
